England’s last submarine built during World War Two needs £1.5 million ($2.7 million) to avoid ending up on the scrapheap of history.

The HMS Alliance was launched just weeks before the end of the war and never saw action. It is the last surviving Amphion class submarine specially designed for long-range Pacific warfare. While it missed the big show, it saw active service until 1973. Now it’s the central display at the Royal Navy Submarine Museum in Gosport, Hampshire, in England.

The HMS Alliance survived its active service unscathed, but is now in sorry shape. Pigeons nest in its corroded hull, and parts of it are actually falling off. Already £4.6 million ($7 million) has been raised for an emergency overhaul, but without the additional funds the submarine will no longer be suitable as a museum.

The Royal Navy Submarine Museum chronicles the history of the UK’s submarine fleet from 1901 to the present day, especially its key role in defending Britain during both world wars. A memorial to the 5,300 personnel who gave their lives in the submarine service is a centerpiece of the museum. Also on display is the Holland I, the Royal Navy’s first submarine, launched in 1901.
